Replace WebAssembly feature CLI options with --wasm-features.

Browse Source 
This commit hides the existing WebAssembly feature CLI options (e.g.
`--enable-simd`) and adds a `--wasm-features` flag that enables multiple
(or all) WebAssembly features.

Features can be disabled by prefixing the value with `-`, e.g.
`--wasm-features=-simd`.

`--wasm-features=-multi-value`.
* Breaking: the CLI option `--enable-bulk-memory=false` has been changed to
`--disable-bulk-memory` as it is enabled by default.
`--wasm-features=-bulk-memory`.
* Modules serialized with `Module::serialize` can now be deserialized with
`Module::deserialize` on a compatible host that does not have to match the
